9-(9-8x)=2x+3

simplify -72x+81=2x+3

subtract 2x from both sides -74x+81=3

subtract 81 from both sides -74x=-78

divide by -74 on both sides x=39/37

Given the formula C= 1/2t(c1-c2), solve for t.
kobusy [5.1K]

Answer:

t=\frac{2C}{c1-c2}

Step-by-step explanation:

C=\frac{1}{2}t(c1-c2)\\2(C)=2(\frac{1}{2}t(c1-c2))\\2C=t(c1-c2)\\\frac{2C}{c1-c2}=\frac{t(c1-c2)}{c1-c2}\\t=\frac{2C}{c1-c2}

Which is the completely factored form of 12x3 – 60x2 4x – 20? 4(3x2 – 1)(x – 5) 4x(3x2 1)(x – 5) 4x(3x2 – 1)(x 5) 4(3x2 1)(x – 5
Neporo4naja [7]

The factors of the polynomial are \rm  4(3x^2 + 1)(x-5).

<h3>Factorization;</h3>

Factorization is nothing but writing a number as the product of smaller numbers.

Given

Polynomial;\rm 12x^3 - 60x^2 + 4x -20

To find the factorization the polynomial equates the equation with zero following all the steps given below.

Then,

The factor of the polynomial is;

\rm 12x^3 - 60x^2 + 4x -20\\\\ 12x^3(x-5)+4(x-5)\\\\(12x^3+4)(x-5)\\\\ 4(3x^2 + 1)(x-5)

Hence, the factors of the polynomial are \rm  4(3x^2 + 1)(x-5).

Figure out the pattern, and write the next number.<br> 2,6,21,88
bija089 [108]
Answer:
a5=445

Explanation:
a of n=(a+1)*n
a1=2
I found the pattern to add 1 to the previous number and then multiply it by its number in the sequence. Apologies for the terrible format of my recursive formula.
Proof of pattern:
(2+1)*2=6
(6+1)*3=21
(21+1)*4=88
a5=(88+1)*5=445
